This kit was originally issued in 1976, but don't let that stop you from building this awesome model. Yes, it's expensive - but it's worth it.

The main part of the chassis is a large one-piece unit that includes the front inner fenders and interior platform-style floor pan.

The interior includes working brake and clutch pedal assemblies with photo-etch pedal faces, shifter assembly, and seat mounting brackets attached before moving on to the suspension.

The front suspension includes the front working shocks and nice disk brakes, including photoetched brake faces. The rear suspension also has working shocks, and disk brakes with photoetched faces.
The engine is the jewel of this kit. With a little extra detailing, it could be displayed as a model by itself. Many of the oil/fuel lines are molded in a soft vinyl, but because there is no "wire" inside, they don't stay put, and they don't look realistic. I recommend replacing them with wire or tubing.

Attaching the turbo and exhaust requires a lot of test-fitting of the parts. Photoetched exhaust flanges glue to the bottom of the engine, but the exhaust attachment pins wouldn't fit through the holes in the photoetched piece; you'll have to thin the pins a little bit.
The steering wheel is assembled with a working steering column and vinyl U-joints that are supposed to allow the steering to function; but I had difficulty getting the parts to fit correctly, then the assembly didn't seem long enough to reach the steering rack. I ended up gluing the pieces in place.

I wish Tamiya would have included two sets of seat belts for a street version.

The body parts fit fairly well, but have a few sink marks to fill and sand smooth. There is no drip rail over the side window/door; it can be made from styrene stock.
The clear window pieces attach with screws and brackets, but at the attachment points the windshield and rear window have "waviness," and the brackets are visible after final assembly.

The vinyl trim parts on the body don't sand well, don't hold paint well, and show the areas where you trim the part away from the sprue. They are meant to snap- or press-fit in place, but the pressure of the fit seems to push the parts out of place. I'd rather have the parts in regular styrene, and paint them myself.

The doors snap to the body of the car and fit fairly well when closed. They're held closed by the vinyl door panel, which creates some pressure against the jamb when closed.
The wheels are three-piece units that make painting and detailing easy, but the chrome plating is too shiny. I stripped the chrome and repainted them with chrome paint.

I loved building this kit, and I'm glad I got the opportunity to do so. I've already started another one!
